Tetramethylammonium t-butyl hydrogenphosphite (2), readily available from the reaction between di-t-butyl phosphite and aqueous tetramethylammonium hydroxide, was found to be a convenient phosphorylating agent for organic halides. It reacts easily with alkyl iodides and some alkyl bromides in boiling acetone affording the corresponding alkyl t-butyl phosphites (3). On treatment with trifluoroacetic
The present invention relates to a novel class of guanine nucleotide analogs which inhibit RelA and Relseq synthetic activity and which possess anti-bacterial activity. The present invention also relates to pharmaceutical compositions that include such compounds, and to methods of use of such compounds or compositions for combating bacteria and treating bacterial infections.
